As ilhas oceânicas do Golfo da Guiné apresentam uma ampla diversidade de condições ambientais e de comunidades biológicas, cujas interacções têm contribuído para o desenvolvimento de uma grande variedade de ecossistemas, desde mangais a pradarias de montanha. As actividades humanas alteraram extensa e profundamente muitos destes ecossistemas natura...
As ilhas oceânicas do Golfo da Guiné (Príncipe, São Tomé e Ano-Bom) constituem um centro de endemismo excepcional para flora e fauna. Nas últimas décadas têm sido feitos progressos notáveis na investigação biológica: desde espécies descritas e identificadas pela primeira vez, a padrões gerais de associações de habitat encontrados em espécies terres...
Conservation translocations are a well‐known conservation tool used to reverse the effects of local population extinctions and restore ecosystems. Compared with mammals and birds, plants are underrepresented in translocation programs, and little is known about the potential taxonomic and phylogenetic biases of plant translocation efforts. We aimed...
Aim
We map global patterns of taxonomic and functional change between past (pre‐human impacts) and present (after anthropogenic extinctions and introductions) in large oceanic island bird assemblages and investigate if these patterns can be explained by island characteristics and anthropogenic factors.
Location
Sixty‐four oceanic islands (>100 km...
Motivation
Human activities have been reshaping the natural world for tens of thousands of years, leading to the extinction of hundreds of bird species. Past research has provided evidence of extinction selectivity towards certain groups of species, but trait information is lacking for the majority of clades, especially for prehistoric extinctions...

Invasive non‐native species (INS) continue to pose a significant threat to biodiversity, including native population declines, which can ultimately disrupt ecosystem processes. Although there is growing evidence of the impacts of INS on functional diversity, most of the existing approaches to prioritization of species for conservation still focus o...
Humans have been driving a global erosion of species richness for millennia, but the consequences of past extinctions for other dimensions of biodiversity-functional and phylogenetic diversity-are poorly understood. In this work, we show that, since the Late Pleistocene, the extinction of 610 bird species has caused a disproportionate loss of the g...
Since it was first described in 1901, the Príncipe thrush Turdus xanthorhynchus has been rare and restricted to the native forest in the south of Príncipe Island. The Obô giant land snail Archachatina bicarinata, however, was widespread across the island and at least locally abundant until the 1990s. Since then its population has collapsed, and now...
Research on island species–area relationships (ISAR) has expanded to incorporate functional (IFDAR) and phylogenetic (IPDAR) diversity. However, relative to the ISAR, we know little about IFDARs and IPDARs, and lack synthetic global analyses of variation in form of these three categories of island diversity–area relationship (IDAR). Here, we undert...
Oceanic islands are among the most transformed ecosystems in the world, with many having experienced major biotic changes through the combined effects of species extinctions and introductions. We map global patterns of taxonomic and functional change in 64 oceanic island bird assemblages and investigate whether these patterns can be explained by ei...
The oceanic islands of the Gulf of Guinea display a large diversity of environmental conditions and biological communities, whose interactions have contributed to the development of a great variety of ecosystems, from mangroves to montane grasslands. Human activities have extensively and profoundly altered many of these natural ecosystems over the...
The oceanic islands of the Gulf of Guinea (Príncipe, São Tomé, and Annobón) are an exceptional centre of endemism for flora and fauna. Remarkable progress has been made in biological research during the last few decades: from species being described and reported for the first time, to general patterns of species-habitat associations found across te...
Humans are quickly reshaping species assemblages through the loss and gain of species at multiple scales. Extinctions and introductions are non‐random events known to be contributing to taxonomic homogenization. However, it is not yet clear if they also promote functional homogenization. Here, we assess whether extinctions and introductions are lea...
Aim
The world's islands support disproportionate levels of endemic avian biodiversity despite suffering numerous extinctions. While intensive recent research has focused on island bird conservation or extinction, few global syntheses have considered these factors together from the perspective of morphological trait diversity. Here, we provide a glo...
Aim
We analyse the consequences of species extinctions and introductions on the functional diversity and composition of island bird assemblages. Specifically, we ask if introduced species have compensated the functional loss resulting from species extinctions.
Location
Seventy‐four oceanic islands (> 100 km ² ) in the Atlantic, Pacific and Indian...
Localizada no interior norte de Portugal, a Paisagem Protegida da Albufeira do Azibo foi criada pelas autoridades portuguesas para preservar um rico ambiente natural, lar de inúmeras espécies de fauna e flora. Posteriormente, foi criada na albufeira uma área de lazer com duas praias públicas receptoras do galardão ambiental Bandeira Azul. Neste art...
Aim
We analyse the functional consequences of the changes in species composition resulting from extinctions and introductions on oceanic island bird assemblages. Specifically, we ask if introduced species have compensated the functional loss resulting from species extinctions.

Located in the interior North of Portugal, the Azibo Reservoir Protected Landscape was created by the Portuguese authorities to preserve a rich natural environment, home of numerous species of fauna and flora. Later, a recreational area was created in its reservoir, with two public beaches that were awarded the Blue Flag eco-label. In this paper, t...
Aim
Few bird extinctions on oceanic island have been attributed to competition with non-native species, even though it might be an overlooked driver of biodiversity loss. We evaluate the potential competition between native and non-native island bird species, identifying species and island characteristics that enhance it and may promote future exti...
Habitat loss and non-native species are two key drivers of biodiversity decline. The importance of their interactions is widely recognized, but remains poorly understood. We used the endemic-rich bird assemblage of São Tomé Island to study this type of interactions. We built species-specific binomial generalized linear models for 33 terrestrial bir...
Introdução e objetivos - Os estudos parasitológicos das populações silvestres têm sido negligenciados, embora inúmeras espécies de parasitas apresentem ciclos que envolvem hospedeiros domésticos e silvestres, sendo a sua compreensão fundamental para entender a sua epidemiologia sob o conceito de “One Health”. Para caraterizar a situação epidemiológ...
Biodiversity is experiencing a rapid decline at a global scale. Habitat loss, associated with
anthropogenic land-use change, and introduced species are two of the main causes of
biodiversity loss. Although it is recognized that these two causes can interact, the
consequences of this interaction are still under-studied. This project used the oceanic...
Tropical forests are some of the most diverse and threatened terrestrial ecosystems. The increasing human pressure, high number of threatened species and major habitat loss forces conservation action prioritization. São Tomé is a small oceanic island with an endemic-rich avifauna. It has a single protected area: The São Tomé Obô Natural Park (STONP...
The loss of native biodiversity is a major consequence of the introduction of invasive species. This process has larger repercussions when it occurs in restricted areas with high levels of endemism, such as islands. Knowing the ecology of invasive species, namely their habitat preferences, distribution and potential interactions with local biodiver...
